[Osseointegrated implants. Clinical cases and light and electron microscope study]. / Implantes oseointegrados. Casos clínicos y estudio de microscopia óptica y electrónica.

Titanium osseointegrated implants have been placed in maxilaries of partially edentulous patients. After a follow-up of 5 to 6 months, a clinical and radiographical evaluation was made in order to determine the osseointegration obtained. In two of these cases, the gingival tissue in contact with the implants was studied under a light and transmission electron microscope. The results indicated a high percentage of implants were osseointegrated (99.72%), and the microscopical analysis showed a tissular reaction denoting biocompatibility with the implants.

[Subperiosteal mandibular implant. Clinical cases and microscopic study]. / Implante subperiostico mandibular. Casos clinicos y estudio microscopico.

Subperiosteal surgical Vitallium implants have been set in the mandible of patients with loss of height of the osseous ridge and difficulty in the use of prostheses obtaining very good clinical and radiographical results. The optic microscopy showed a great tendency of adhesion of the gingiva's junctional epithelium to the implant.
